fatigue analysis using ABAQUS

I am new ABAQUS user, i want to learn ABAQUS for the analyis of failure of material i.e fracture, creep and fatigue. my aim is get analysis of a fatigue analysis of rotating and bending welded alloy. can you please help me in doing this analysis on ABAQUS.........please send any fatigue tutorial of ABAQUS..

ABAQUS/CAE simulating surface wave

hello, I am an MTech NDT student. I would like to know how to create a node set for transmitting and recieving ultrasonic surface wave through a 2D deformable sheet and through a 3D bar, using ABAQUS/CAE

Journal Club Theme of April 2012: Phononics: Structural Dynamics of Materials

Engineering structures are made out of materials and as such there is a natural hierarchy in which a material’s intrinsic properties contribute to shaping up the structure’s response. It is possible however to reverse this hierarchy and engineer materials that are made out of structures. In this case, the intrinsic properties of a material are shaped by the structural response. Such a configuration can only be realized with a repeated structure, forming an array of identical unit cells.

sir, i need help to make glass fibre composite dcb specimen by using ansys&which element is suitable for making this.

Spectacular torsional-flexural autovibrations of a Volga bridge

The autovibrations of the bridge over Volga river in the city of Volgograd(Russia) were filmed (not by me) today on 05/21/2010. The amplitude reachedabout 1 m. The bridge opening was just six months ago...

Apparently, either the bridge frame drag was too high or torsional stiffness / damping too low.

Collapse of the Tacoma Narrows Bridge, 7 November 1940

In today's class of complex analysis, my co-instructor Scott Norris was lecturing on resonance.  He mentioned a YouTube video of the Tacoma Narrows Bridge.  Also instructive is the entry of the bridge on Wikipedia

Everything is miscellaneous (Video)

While preparing a talk on iMechanica , I came across the following video "Information R/evolution" by Michael Wesch, an assistant professor of anthropology at Kansas State University.  This thought provoking video echoes a recent comment on "The future of knowledge?"

Enjoy!
